Observe, however, that tho veining of the leaf (Fig. 83) is different, that of Calla being straight, like the Dog's-tooth Violet. There is also a difference in the flowers. Those of Indian-Tur- nip were found to be dioecious, but the spadix, in the present case, bears both stamens and pistils, and the lower flowers, if not all, are perfect; some- times the upper ones consist of stamens only. Fig. 84 shows one of the perfect li flowers much enlarged. The stamens, it will be observed, have two-celled anthers, opening lengthwise. MARSH Fig. 84. ORGAN. NO. COHESION ADHESION. Perianth.

The flower of this plant (Figs. 85, 8G) is provided with floral envelopes, all col- oured like a corolla. As in Dog's-tooth Violet, we shall call them collectively the perianth, although they are not all alike. One of them projects forward in front of the flower, forming the lip, and bears under- neath it a long hollow spur, which, like the spurs of Columbine, is honey-bearing. The remaining five con- verge together forming a kind of arch over the centre of the flower. Each flower springs from tho axil of a.
